Halfway down the peninsula, the desert does something impossible: an underground river surfaces into a lagoon ringed by a hundred thousand date palms, and a lava-stone mission town sits in the middle of it. San Ignacio would justify the drive by itself. But it’s also the gateway to the Sierra de San Francisco — the UNESCO-listed canyons where the Great Mural rock art covers cave walls with life-size figures painted across some 7,500 years — and that combination makes this the library’s deepest trip in every sense.
